• Return cell reference as result of if statement with vlookups.

  - by EMJ

  I have two sets of data in excel. One contains a set of data which represents the initial step of a process. The other set of data represents the additional steps which take place after the first step is completed. Each of the data records in the "additional step data" has an id in a column. I need to find the identifying codes of the "additional step data" which correspond with the initial step data records. The problem is that I have to match the data in 4 columns between the two data sets and return the id of the "additional step data". I started by doing a combination of an if and vlookup functions, but I got stuck when I tried to figure out how to get the if statement to reference the id of the matching "additional step data". Basically I am trying to avoid having to search by manually filtering between two sets of data and finding corresponding records. Does anyone have any idea about how to do this?

• C# IF statement against SQLite query result

  - by jakesankey

  I have a C# application that I am attempting to check my sqlite db if a filename already exists in the FileName column, if it DOESN'T exist, execute some code.. Here is what I am working with. string[] files = Directory.GetFiles(@"C:\Documents and Settings\js91162\Desktop ", "R303717*.txt*", SearchOption.AllDirectories); foreach (string file in files) { string FileNameExt1 = Path.GetFileName(file); insertCommand.CommandText = @" SELECT * FROM Import WHERE FileName == FileNameExt1;"; } string contYes = insertCommand.ExecuteNonQuery(); if (string.IsNullOrEmpty(contYes)) { //more code } EDIT: added space in path so that slash doesn't eat quotation mark

• Finding records within a 5 min time interval in SQL

  - by Mellonjollie

  I have a table with over 100,000 rows that contain the following columns: ID, Time, and Boolean. The time column tracks time down to the second. I need a query that will find all instances of Boolean = 1 for every 5 minute interval of time from the start of the table to the end, then group the count by time interval. The table represents 4 hours of data, so I should get 48 rows of results. I'm using MS SQL Server. I've tried a few approaches, but the time interval logic is giving me a hard time.

  I would like to split a column of strings on the first two colons, but not on any subsequent colons: my.data <- read.table(text=' my.string some.data 12:34:56:78 -100 87:65:43:21 -200 a4:b6:c8888 -300 11:bb:ccccc -400 uu:vv:ww:xx -500', header = TRUE) desired.result <- read.table(text=' my.string1 my.string2 my.string3 some.data 12 34 56:78 -100 87 65 43:21 -200 a4 b6 c8888 -300 11 bb ccccc -400 uu vv ww:xx -500', header = TRUE) I have searched extensively and the following question is the closest to my current dilemma: Split on first comma in string Thank you for any suggestions. I prefer to use base R.

• What machine learning algorithms can be used in this scenario?

  - by ExceptionHandler

  My data consists of objects as follows. Obj1 - Color - shape - size - price - ranking So I want to be able to predict what combination of color/shape/size/price is a good combination to get high ranking. Or even a combination could work like for eg: in order to get good ranking, the alg predicts best performance for this color and this shape. Something like that. What are the advisable algorithms for such a prediction? Also may be if you can briefly explain how I can approach towards the model building I would really appreciate it. Say for eg: my data looks like Blue pentagon small $50.00 #5 Red Squre large $30.00 #3 So what is a useful prediction model that I should look at? What algorithm should I try to predict like say highest weightage is for price followed by color and then size. What if I wanted to predict in combinations like a Red small shape is less likely to higher rank compared to pink small shape . (In essence trying to combine more than one nominal values column to make the prediction)

• Categorized SharePoint Discussion - default category to parents category on reply.

  - by Greg Ogle

  I have a Discussion Board in a SharePoint site which has an additional column named Category. When a new discussion is created, it prompts for Category, and of course this is by design. The problem is that when the discussion is replied to, it prompts for the category again. How can I separate the reply functionality so that the Category is not prompted and the Category is set to that of the discussion under which it resides? I attempted to edit a copy of NewForm.aspx in SharePoint Designer, but you can only edit which WebPart it is using, not which fields are displayed.

• GUID not being generated automatically when db.submitchanges()

  - by BlindingDawn

  I have a couple of tables I ported over to a new database. Everything is exactly the same from the legacy one to the new one. The back-end code that submits the user generated data to the database is also the same. When I submit changes to the database, all of the submitted information populates the correct columns but the column that stores the GUID populates with all 0's. When I enter in the columns manually using SQL Server Management Studio, the GUID gets populated as it does in the legacy version. Am I missing something?

• ASP MVC ViewData from one view to another (Html.Encode())

  - by Jacob Huggart

  Hello all, I have a page with a bunch of labels and checkboxes on it. On this page, the labels need to be easily customizable after the project is deployed. So I made all of the labels in this style: Html.Encode(ViewData["lblText"]) And I added a button on the page called "Edit Button Labels" that will only be seen by admins. When that button is clicked, I would like to load another view that simply contains a table of two columns. One column needs to contain the current labels and the other should have text boxes for the user to enter new labels. Then, once any changes have been made, I need to permanently change the "lblText" for each label on the original page. I have tried passing viewdata and tempdata to the "Edit Button Labels" view using both return view() and return RedirectToAction() with no success. Am I missing something minor or is there a better way to do this?

• Is there a way to use XDocument in the Application Settings?

  - by Shimmy

  I have to store a complex type in the application settings. I thought that storing it as XML would work best. The problem is I don't know how store XML. I prefer to store it as a managed XML rather than using just a string of raw XML having to parse it on each access. I managed to set the Type column of the setting to XDocument, but I was unable to set its value. Is there a way to use XDocument or XML in application settings?

• Best way in Python to determine all possible intersections in a matrix?

  - by ssweens

  So if I have a matrix (list of lists) of unique words as my column headings, document ids as my row headings, and a 0 or 1 as the values if the word exists in that particular document. What I'd like to know is how to determine all the possible combinations of words and documents where more than one word is in common with more than one document. So something like: [[Docid_3, Docid_5], ['word1', 'word17', 'word23']], [[Docid_3, Docid_9, Docid_334], ['word2', 'word7', 'word23', 'word68', 'word982']], and so on for each possible combination. Would love a solution that provides the complete set of combinations and one that yields only the combinations that are not a subset of another, so from the example, not [[Docid_3, Docid_5], ['word1', 'word17']] since it's a complete subset of the first example. I feel like there is an elegant solution that just isn't coming to mind and the beer isn't helping. Thanks.

• Why is selecting specified columns, and all, wrong in Oracle SQL?

  - by TomatoSandwich

  Say I have a select statement that goes.. select * from animals That gives a a query result of all the columns in the table. Now, if the 42nd column of the table animals is is_parent, and I want to return that in my results, just after gender, so I can see it more easily. But I also want all the other columns. select is_parent, * from animals This returns ORA-00936: missing expression. The same statement will work fine in Sybase, and I know that you need to add a table alias to the animals table to get it to work ( select is_parent, a.* from animals ani), but why must Oracle need a table alias to be able to work out the select?

• Adding index key in Grails' Domain

  - by firnnauriel

  I tried following this reference and this is now my domain's code: class SnbrActVector { long nid String term double weight static mapping = { version false nid index:'Nid_Idx' } static constraints = { term(blank:false) } } What I want is to do is to add an index key for 'nid' column. I dropped the existing table and run the app again so the table is then recreated. However, when i check for list of indices, I can't see a 'Nid_Idx', only available is 'PRIMARY'. Do I have to manually create the index and name it 'Nid_idx in my mysql database? Thanks.

• In Android, does _id have to be present in any table created?

  - by Andy

  I am trying to create a table to only has a foreign key, not a primary key. I am getting this error: java.lang.IllegalArgumentException: column '_id' does not exist I read a tutorial that the primary key must be _id, with no explanation. And that is fine. But what if I do not want a primary key! What if I only want a foreign key. I am assuming this is where my problem lies. The schemas below are what I have. But the third one is where I assume this is coming from. database.execSQL("CREATE TABLE events (" + "_id INTEGER PRIMARY KEY, event_name TEXT" + ")"); database.execSQL("CREATE TABLE reminders(_id INTEGER PRIMARY KEY, event_name TEXT" + ")"); database.execSQL("CREATE TABLE events_info (_id INTEGER, event_name TEXT, all_day INTEGER, " + "start_date INTEGER, start_time INTEGER, end_date INTEGER, end_time INTEGER," + " location TEXT, reminder_id INTEGER, notes TEXT, repeat TEXT," + "FOREIGN KEY(_id) REFERENCES events(_id), FOREIGN KEY(reminder_id) REFERENCES reminders(_id))" );

• Horizontal scroll in rich:panel to default right to left

  - by TaylorSmolik

  I have a rich:panel with a style="overflow: scroll" tag inside. By default, the scroll slides left to right. I am constantly adding a new dataTable to a dataGrid with the click of a button and I want the user to always see the most recent one, and since I have it set up so that each dataTable is added as a column to the dataGrid, the most recent one will always be on the right side of the dataGrid. Is there a way I can default the scroll to go right to left? Or maybe creating the columns from right to left?

• Should I use a huge composite primary key or just a unique id?

  - by Jack

  I have been trying to do web scraping of a particular site and storing the results in a database. My original assumptions about the data allowed a schema where I could use fairly reasonable composite primary keys (usually containing only 2 or 3 fields) but as time went on, I realized that my original assumptions about the data were wrong and my primary keys were not as unique as I thought they were, so I have slowly been expanding them to contain more and more fields. In fact, I have recently come to believe that their database has no constraints whatsoever. Just today, I have finally expanded my a primary key for one of my tables to contain every field in that table and I thought now would be a good time to ask: is it better to add an auto-incrementing column that is just a unique id or just leave a composite primary key on the entire table?

• parsing position files in ruby

  - by john

  I have a sample position file like below. 789754654 COLORA SOMETHING1 19370119FYY076 2342423234SS323423 742784897 COLORB SOMETHING2 20060722FYY076 2342342342SDFSD3423 I am interested in positions 54-61 (4th column). I want to change the date to be a different format. So final outcome will be: 789754654 COLORA SOMETHING1 01191937FYY076 2342423234SS323423 742784897 COLORB SOMETHING2 07222006FYY076 2342342342SDFSD3423 The columns are seperated by spaces not tabs. And the final file should have exact number of spaces as the original file....only thing changing should be the date format. How can I do this? I wrote a script but it will lose the original spaces and positioning will be messed up. file.each_line do |line| dob = line.split(" ") puts dob[3] #got the date. change its format 5.times { puts "**" } end Can anyone suggest a better strategy so that positioning in the original file remains the same?

• How to insert a value based on lookup from another table [SQL]?

  - by Shaitan00

  I need to find a way to do an INSERT INTO table A but one of the values is something that comes from a lookup on table B, allow me to illustrate. I have the 2 following tables: Table A: A1: String A2: Integer value coming from table B A3: More Data Table B: B1: String B2: Integer Value Example row of A: {"Value", 101, MoreData} Example row of B: {"English", 101} Now, I know I need to INSERT the following into A {"Value2", "English", MoreData} but obviously that won't work because it is expecting an Integer in the second column not the word "English", so I need to do a lookup in Table B first. Something like this: INSERT INTO tableA (A1, A2, A3) VALUES ("Value2", SELECT B2 FROM tableB where B1="English", MoreData); Obviously this doesn't work as-is ... Any suggestions?
